Updated 1:20 p.m. August 1 with reopening of smelter

The Doe Run Peru smelter in La Oroya, which had been clsoed due to financial and environmental compliance issues since 2009, resumed zinc processing operations over the weekend.

Peru's Minister of Energy and Mines, Jorge Merino Tafur, is reported to have said that lead smelting would also resume in the not too distant future. Restarting copper production would likely take longer, since that would require building a plant to control sulfuric acid emissions.

Doe Run Peru is owned by the Renco Group, which also owns the St. Louis-based Doe Run Resources Corporation. The metal smelting companies in Missouri and Peru have operated independently since 2007.

Unlike their cold-weather relatives, Humboldt penguins live only in South America, along the rocky Pacific coast of Chile and Peru.

The Saint Louis Zoo’s Michael Macek has been monitoring the penguins there, tracking their health and numbers.

Macek is back in Peru again, in a coastal reserve called Punta San Juan, where Humboldt penguins nest by the thousands.

Before he left, he told St. Louis Public Radio's Véronique LaCapra that this time he’s helping to lead a sustainable guano harvest.
